Small-scale magnetic helicity losses from a mean-field dynamo

Axel Brandenburg, Simon Candelaresi, Piyali Chatterjee

Using mean-field models with a dynamical quenching formalism we show that in finite domains magnetic helicity fluxes associated with small-scale magnetic fields are able to allevia…

Dust and the type II-plateau supernova 2004et

Rubina Kotak, Peter Meikle, Duncan Farrah +14

We present mid-infrared (MIR) observations of the Type II-plateau supernova (SN) 2004et, obtained with the {\it Spitzer Space Telescope} between days 64 and 1406 past explosion. La…

The alpha effect with imposed and dynamo-generated magnetic fields

A. Hubbard, F. Del Sordo, P. J. Käpylä +1

Estimates for the nonlinear alpha effect in helical turbulence with an applied magnetic field are presented using two different approaches: the imposed-field method where the elect…

Axial quasi-normal modes of neutron stars: Accounting for the superfluid in the crust

Lars Samuelsson, Nils Andersson

We present the results of the first study of global oscillations of relativistic stars with both elastic crusts and interpenetrating superfluid components. For simplicity, we focus…

Observational and theoretical constraints for an H-halo around the Crab Nebula

A. Tziamtzis, M. Schirmer, P. Lundqvist +1

We searched for a fast moving H shell around the Crab nebula. Such a shell could account for this supernova remnant's missing mass, and carry enough kinetic energy to make SN 10…

The role of the Yoshizawa effect in the Archontis dynamo

Sharanya Sur, Axel Brandenburg

The generation of mean magnetic fields is studied for a simple non-helical flow where a net cross helicity of either sign can emerge. This flow, which is also known as the Archonti…
